MACHINE FOR FILLING BRISTLES IN BACKS OF BRUSHES.

SPECIFICATION forming part of Letters Patent No 790,147, dated May 16,1905.

Application led October 15, 1903. l Serial No. 177,158. l l

To MZ whom t may col/warn.-

Troy, in the county of Rensselaer and State of New York, have inventednew and useful Improvements in Machines for Filling Bristles in Blocksof Brushes, of which the following is a specification.

This invention relates to machines for filling blocks of brushes withbristles and in bunched condition for cementing them in place; and itconsists in the novel devices and the novel combinations andarrangements of devices and parts hereinafter described, and set forthin the claims.

The objects of this invention are to provide mechanism for effectingmechanical operations with mixed and tangled bristles, which maydiscntangle the bristles, straighten them out, and graduallyT changetheir position from horizontal to vertical for passage through thenumerous bristle-conductors (provided in a suitable bristle-conveyerplate) and into bunch receiving holes -provided in brushblocks as theyare commonly prepared.,

Other purposes and advantages will be clearly understood from thefollowing description, when taken in connection with the accompanyingdrawings, in two sheets, forming a part of this specification, in which-Figure l is a plan of a machine embodying the improvements with theupper bed of revoluble shafts and arms in part broken away for exposingthe parts of the lower bed of vibratory shafts and arms. Fig. 2 is alongitudinal section Online 2 2, Fig. 3. Fig. 3 is an end elevation,(left hand.) Fig. 4 is an end elevation, (right hand.) Fig. 5 is asection taken at line 1 in Fig. 2. Fig. 6 is a plan of abristle-conductor plate, and Fig. 7 is a secy tion of the same and abrush-block in place beneath on line 7 7.

Similar letters of reference refer to similar parts throughout theseveral views.v

A is a receptacle into which bristles are a bed formed by a series ofvertically-,vibratory devices C, the latter devices being arranged on aplane below the former.

The revoluble devices B consist of a series of longitudinal cylindricalshafts of suitable diameter, as, say, ve-sixteenths of an inch, or moreor less, as may be found to be most advantageous for carrying each aseries of suitable arms. These revoluble. devices B comlprise each ashaft b, to each of which is secured several series of radial arms o' o.and b2 o2, which latter are'relatlvely at an angle with the former, asshown in Fig. 5, and these` shafts are so arranged in relation to eachother that one set of shafts have their arms o' b and o2 b2 vertical andhorizontal, whilethe arms of the alternating shafts are diagonal. Ofcourse when these shafts are revolved the relative positions of the armswill be constantly changing. The arms o o of each shaft are in alinementwith each other, whilev arms Z22 o2 are in alinement with each other,but out of aline- Inent with arms o b of the same shaft and those of theadjoining shafts, so that the arms of one shaft may freely pass those ofits adjoining shafts and also produce suitable openings for free passageof bristles from above to vibratory mechanisms below. These revolubledevices B are continuously revolved byl means of a series of cog-wheelsC C', secured to the outer ends of shafts o b.

' Below the bed of the series-of revoluble devices is arranged the bedof series of vibra? those of their 1adjoining shafts, so that theyv maypass each other at a distance of onefourth of an inch apart or more orless, as may be found to be advantageous. These vibratory devices are.vibrated vertically by any suitable mechanism, yet I prefer to employcog-wheels D D similar to cog-wheels C C for that purpose. Thesecog-wheels D are secured to the outer ends of the shafts c at one end ofthe machine, with the eogs of each wheel working in between the cogs ofthe adjoining wheels, and they are simultaneously turned about theiraxes to a distance of less than one-half of a full revolution with eachalternating cog-wheel turning in opposite direction to their adjoiningcog-wheels, so that each alternating vibratory device C may have itsarms cl 02 vibrated in reversed direction continuously, with the arms ofeach shaft passing those of the other at short distances apart.

E is a driving-wheel secured, preferably, on the rearward shaft of theseries of revolving devices B and at one end of the receptacle, as shownin Figs. l and 2. This drive-wheel may be actuated from any source ofpower or motion, and when revolved continuously will, through the seriesof gear-wheels C C, revolve all the shafts of the revolving devices Bsimultaneously with adjoining shafts moving in opposite direction.

F is an actuating-wheel arranged at the opposite outer end of themachine, which wheel is driven from any suitable source of power ormotion and is mounted on a suitable spindle secured to the said end ofthe machine.

Pivoted on the outer end of one of the shafts' of the vibratory devicesC, and preferably on the rearward shaft of the series, which may beprojected to a sufficient distance out past the cog-wheel D fixedthereon, is a vibrating arm Gr. A connecting-rod g connects thewrist-pin of said actuating-wheel F with the upper end of said arm Gbymeans of pivots g g2, respectively.

H is a vibrating arm pivoted, preferably, on the first vibratingcog-wheel D and preferably depending from the same, as shown in Figs. 2and 3. This vibrating arm H is connected at its lower end withvibratingarm G by means of connecting-rod 7L at a point about midwaybetween its lower end and its upper end, pivoted on connecting-rod g.Then actuating-arm F is revolved to carry wrist-pin g' around the centerof said wheel, the connecting-rod g will have imparted to itareciprocating movement, and thereby vibrate arm G, which in its turnwill impart to connecting-rod /L an end wise-reciprocating movement, andthereby vibrate arm H, which arm being secured to one of the cog-wheelsD vibrates the cog-wheel secured to it and through said wheel all theother cog-wheels D in the series, and imparts to the vibratory devices Ca vibratory motion in which the arms c' and c2 of each adjoining shaft cmoving alternately in opposite direction to the limit permitted by thelength of movement of the vibrating arm H. The length of movement ofvibrating arm may be changed by changing the points of pivotalconnection of connectingrod /t with vibrating arm H and arm Gr by meansof pivot-holes 72. and /1/2, provided in said arms H and G. (Shown inFig.

l l, Figs. Z and 5, designate an adjustable track secured to verticaladjustable tongues l', which are properly guided between guidopieees l212 and are secured in places adjusted to by clamping-bolts l, passingthrough slotform opening vf, provided in each vertical tongue andholding by its head with said tongues and passed through end pieces ofthe machine and provided with a suitable thumbnut for tighteningorloosening the same,as may be required. These tracks I I support amovable rack or bed J, which maybe moved from the projected end portionsof the same inward beneath the series of revolving devices l and seriesof vibratory devices l) and may be moved vertically to near the latterdevices or farther from the same, as the length ol the bristles operatedwith may require for best operations and results.

The manner in which the parts in this machine operate is as follows: Thetracks .l and bed J will be adjusted vertically as the length of thebristles to be operated with may require, and the back l( of the brushprovided with the usual bunch-holes will be placed on said bed andbeneath the metalbristle-conveyer plate L, which will be in place upnear to vibratory bed C as the radial arms c' c2 may allow. Revolvingwheel E will now be revolved and revolve all the cog-wheels on the shaftof the revolving devices B. The one-half of the number alternating withthe other will be revolved in one direction and the other half inanother, at the same time actuating-wheel F will be revolved and throughmechanism provided as above described will impart to each alternatevibratory device C a vibratory motion in which the radial arms c' c2 ofeach alternating shaft D will be vibrated vertically in one direction toa sufiicient distance for gradually changing the positions of thebristles from horizontal to vertical or approaching near to vertical asthey are passed down bythe action of the revolving devices B in astraightened and disentangled condition. Portions ol the bristles willnow be passed into the conducting perforations Z, provided in plate L,and from thence into the perforations provided in the brush-blocks K,until all perforations therein have been iilled. When filled, theseblocks K of the brushes will be removed and have cleared from thebristles attending an overflow of the same, when the bunched bristleswill be ready for being secured in place by process of cementing orotherwise.
